Belt-driven conical-pulley transmission with hydraulic system and auxiliary oil source |
摘要 |
A belt-driven conical-pulley transmission contained in the power train of a motor vehicle and having two conical disk pairs encircled by an endless torque-transmitting element. A hydraulic system is provided for pressing the conical surfaces of the conical disks against the endless torque-transmitting means and for opposite adjustment of the spacing between the conical disks for an adjustment of the transmission ratio. The hydraulic system includes a pump driven by an internal combustion engine that propels the vehicle, and the system includes an auxiliary oil source with which a predetermined minimum pressure is maintained in the hydraulic system when the internal combustion engine is shut off.
